Therapeutic jurisprudence (TJ) studies law as a social force (or agent) which inevitably gives rise to unintended consequences, which may be either beneficial (therapeutic) or harmful (anti-therapeutic). These consequences flow from the operation of legal rules or legal procedures—or from the behavior of legal actors (such as lawyers and judges). TJ researchers and practitioners typically make use of social science methods and data to study the extent to which a legal rule or practice affects the psychological well-being of the people it affects, and then explore ways in which anti-therapeutic consequences can be reduced, and therapeutic consequences enhanced, without breaching due process requirements. Early development The term was first used by Professor David Wexler, of the University of Arizona Rogers College of Law and University of Puerto Rico School of Law, in a paper delivered to the National Institute of Mental Health in 1987. Constance Backhouse, a leading legal historian from Canada, has published a biography of Wexler and his work. Along with Professor Bruce Winick of the University of Miami School of Law, who developed the area with Wexler, these law professors suggested the need for a new perspective, TJ, to study the extent to which substantive rules, legal procedures, and the role of legal actors (lawyers and judges primarily) produce therapeutic or antitherapeutic consequences for individuals involved in the legal process. In the early 1990s, legal scholars began to use the term when discussing mental health law, including Wexler in his 1990 book Therapeutic Jurisprudence: The Law as a Therapeutic Agent, and Wexler and Winick in their 1991 book, Essays in Therapeutic Jurisprudence. The TJ Approach soon spread beyond mental health law to include TJ work in criminal law, family and juvenile law, health law, tort law, contracts and commercial law, trusts and estates law, disability law, constitutional law, evidence law, and legal profession. In short, TJ became a mental health approach to law generally. The approach was soon applied to the way various legal actors—judges, lawyers, police officers, and psychologists and criminal justice professionals—play their roles, suggesting ways of doing so that would diminish unintended antitherapeutic consequences and increase the psychological well-being of those who come into contact with these legal figures. In 1999 in a Notre Dame Law Review article TJ was applied to drug treatment courts (DTC) for the first time and the authors asserted that DTCs were TJ in action and that TJ provided
